ISIS pilot program finally launching on T-Mobile Oct. 22

The pilot program will be made available to select T-Mobile customers in Salt Lake City, Utah and Austin, Texas. If you happen to be in one of those cities, you'll also need to have an unrooted Galaxy S III, Galaxy S II, or Galaxy S Relay 4G. If you meet all of those criteria, you would get a special ISIS SIM card to use.
